21) Base your answer on the information below and on your knowledge of chemistry.
A hydrate is a compound that has water molecules within its crystal structure.
Magnesium sulfate heptahydrate, MgSO4.7H20, is a hydrated form of magnesium
sulfate. The hydrated compound has 7 moles of H2O for each mole of MgSO4. When
5.06 grams of MgSO4.7H20 are heated to at least 300.°C in a crucible by using a
laboratory burner, the water molecules are released. The sample was heated
repeatedly, until the remaining MgSO4 had a constant mass of 2.47 grams. During
this laboratory activity, appropriate safety equipment was used and safety
procedures were followed.
Determine the gram-formula mass of the anhydrous magnesium sulfate and the gfm for the
hydrate?
